Hello! Today I've made a new wall. Or converted it at least. (I must be going crazy, wall-making is way too addictive) It was originally by Christing at Parsimonious, but I converted it for use in the sims 3. Anyway, basically I wanted a new wall that would look nice when patterned, so here it is.
It can be found in Build Mode > Walls > Panelling, and it has 2 channels.
